The present invention relates to the technical field of sports equipment, in particular to a dual-fan elliptical machine with an improved pedal structure.

Please refer to Figure 1. The main structure of an elliptical machine on the market includes: a base 11, an air resistance wheel 12, and two transmission rod groups 13. The base 11 can be fixed to the ground, and the air resistance wheel 12 is pivoted on the base 11 , The two transmission rod groups 13 respectively have a foot rod 131 and a grip rod 132. One end of the foot rod 131 is pivoted on the periphery of the wind resistance wheel 12, and the other end of the foot rod 131 is fixedly connected to a The telescopic rope 14, when the wind resistance wheel 12 rotates, the foot lever 131 will swing around the circumference with the wind resistance wheel 12, and one end of the holding rod 132 is pivotally connected to the foot lever 131 to approach the wind resistance wheel At one end of 12, when the foot lever 131 swings with the wind resistance wheel 12, the grip lever 132 will also swing, and the user can step on the foot lever 131 and hold the grip lever 132 , To simulate the exercise of hiking or brisk walking.

However, the foot lever 131 of the aforementioned elliptical machine will only swing along the circumference of the wind resistance wheel 12 with the rotation of the wind resistance wheel 12. The angle at which the user steps on the foot lever 131 is like stepping on a plane, and the actual When performing hiking or brisk walking, a person’s ankle will rotate at different angles with different actions such as stepping on the ground, leaving the ground, or approaching the ground. Generally, the foot lever 131 of an elliptical machine will only follow the wind resistance wheel 12 The user’s ankle will not rotate with the movement when the user steps on it. Therefore, the user who steps on the foot lever 131 will only feel stepping on the undulating plane, which is similar to the simulation of real hiking or fast walking. The movement is very different.

Secondly, since the combination of the foot lever 131 and the stepping member is almost L-shaped, the user stands on the foot lever 131 and holds the grip lever 132 with his hand, so that the user's center of gravity falls on the foot lever On 131, the human body tilts forward slightly in real hiking or brisk walking, so that the center of gravity of the human body is tilted forward. Therefore, its design also makes the center of gravity of the human body very different from the configuration of the center of gravity of the human body during walking or brisk walking.
